The Samsung NX1000 twin camera stereo system takes interchangeable lenses and also has a variable stereo base from normal to hyperstereo. It is a good system to experiment with different lenses.
- Lenses made by Samsung
- Third party lenses with NX mount
- Vintage lenses adapted to fit the NX mount
So when you see focal lengths for the NX system, multiply the values by 1.5x to get a value comparable to a full frame camera lens. For example, the standard 20-50mm zoom lens is equivalent to a 35-75mm lens, which is a fairly standard and not very exciting focal length range.
- Standard 20-50mm f3.5-5.6 (kit) zoom lens. A solid zoom lens that has received good reviews. You need to match the zooms, or find some way to link the lenses. The zoom control rig is easy to rotate. StereoPhoto Maker (SPM) will align images with differences in focal length (just a matter of scale difference), but within limits.
- 16-50mm f3.5-5.6: This was standard I believe with the NX500. It is a compact lens (see picture below) and attractive for its wider end (16mm) and also because it offers image stabilization (turned ON through the menu, one of the few lenses with this ability). However, it is a motorized zoom lens and does not show the focal length outside or on the screen of the NX1000 cameras, so there is no easy way to match the focal lengths from each camera, other than the two ends. Another kit zoom lens is the 18-55mm lens that came standard with the NX300 cameras, I believe.
- 12-24mm f4-5.6 lens, for those into wide angle photography. These fit in the cameras separated at 68mm, which is the shortest possible spacing of the cameras in the z-configuration (see: http://drt3d.blogspot.com/2017/07/putting-twin-samsung-nx1000-camera-rig.html)
- 50-200mm f3.5-5.6: The longest lens by Samsung, useful for wildlife, long distance action, etc. Does not fit the 68mm spaced camera but most likely it will be used with side-by-side cameras. Here is a picture of me with these lenses. I took some nice bird shots and pictures at a baseball game with these lenses.
Matching Focal Lengths: With the 20-50mm lenses, one has to match the focal lengths, if using anything other than the two ends (20mm, 50mm). This is usually done by matching the focal length markings on each lens. This is a bit of a problem in the z-configuration where the left lens is upside down and you cannot see the markings. I have used a marker to mark the back side of upside down lens. Another option is to use some kind of mechanical method to link the zooms. I know a couple of people are working on this. I will update this section when I see an interesting solution.
- Fixed focal length lenses are more compact.
- They are faster (have a large and fixed maximum aperture)
- The focal length cannot be changed accidentally. This is easy to do with the 20-50mm lenses.
An interesting side-effect of using fixed focal length lenses: If I happen to have the 45mm lenses, I change my composition and subject framing, to match the lenses. It is a bit of a challenge to use the lenses that I have on the cameras for any situation I find myself into, and the results are often rewarding (unusual composition, different point of view).
One last comment: I survived 30 years of fixed focal length lenses with my Stereo Realist and RBT S1 stereo camera. Yes, I did try zoom lenses with RBT SLR-type cameras, but soon switched to fixed focal length lenses there too. Zoom lenses are a convenience (carry less weigh, be able to change the focal length to compose better) but at the expense of quality, in my opinion.
- 10mm f3.5 Fisheye: Very tiny!
- 16mm f2.4, a fine performer
- 20mm f2.8, has now become my standard lens
- 30mm f2.0, has received good reviews
- 45mm f1.8, hands down my favorite lens
It is interesting to note that all NX lenses come several colors. The most common are black and white. But there is also pink and silver (the 20mm lens above is silver). The camera bodies also come in different colors (black and white are the most common but I have seen pink too). Some people like to use a different color so they can immediately tell which is the R and which is the L camera/lens. I used to do this too, but not any more. My color of choice for the camera bodies now is white, and black for the lenses.
- 60mm f2.8 macro
- 85mm f1.4, great portrait lens but too large and heavy
[The 20-50mm lens is shown for comparison]
I then attach the matched lens pair to the twin cap. I then use an OP/TECH foldover pouch to store the pair. These are soft, durable, neoprene pouches, that protect the lenses.
Here are all the parts taken apart:
- 8mm f2.8
- 12mm f2.0
- 85mm f1.4
- Adapt the mount (Nikon, etc., on the front, Samsung NX on the back).
- Take care of the infinity focus.
- 50mm f3.5 macro
- 85mm f2.0
- 100mm f2.5
- 100mm f4 macro
- 135mm f2.8 and f3.5
- 200mm f4
- 300mm f4.5 and f5.6
- 500mm f8 (mirror)
These Minolta lenses need to be focused manually (the aperture is also set manually). Because they are longer lenses, focusing is rather critical. It would be nice to have a system that links the focusing rings of the lenses. One feature I use a lot for critical focus is to magnify the image by pressing the center button in the back - see also:http://drt3d.blogspot.com/2017/07/tips-for-using-twin-nx1000-cameras.html
